Xbox and Activision will do NOTHING about this. I've been complaining to them for a year, I haven't been able to play online in a year. They don't care. They just accuse ME of hacking, they don't understand the problem at all and don't care. Boycott them.
Don't renew your Xbox Live membership, and get a different console some day.

I only use it here in the forums. I have a different profile for online game play. There was no action from Xbox or Activision. Activision is "working on it" and have said that for a year. Xbox says it is Activision's problem as they have the data on their
servers. That leaves users with no solution except to pay for another gamer tag just to use CoD 4. R-I-P O-F-F.
